<u>Answer</u>:
1) f(x) = -1/2x+1
I'm sorry I don't know the 2nd one...
<u>Step-by-step explanation:</u>
The y-intercept is always plotted first. from there, you go down one, and to the right too. and so one, and in reverse, up one, and left two.
Are you asking for the whole sheet? But the first would have both P and Q I think would be in in quadrant three. If you want more, just remember that the top right corner is 1, the top left is 2, bottom left is 3, and bottom right is 4.
Answer:
Step-by-step explanation:

Write the equation in factored form.

Separate equations, and set each factor to zero.


Rearrange and isolate the variable to find the solutions


------------------------------------
4!=4*3*2*1=24
11!=11*10*9*8*7*6*5*4*3*2*1=39916800
7!=7*6*5*4*3*2*1=5040
